INDICAT ING AND RECORDING DE VICE.

Specification of Letters Patent. Application filed June27, 1907. SerialNo. 381,061.

To all whom 12 may concern:

- Be it knoxtn that I, JOHN T. 'WnALEN, a citizen of the United Statesof America, and a resident of Brooklyn, in the county of Kings and Stateof New York, have invented certain new and useful Improvements inIndicat mg and Recording Devices, of which the following is aspecification.

This in vuntion relates to speed indicating, regulating and controllingand recording devices, mo1'cpai "'ularly to apparatus of thisdescription which is applicablefand fitted to: vehicles and designedforthe purpose-of in dicating the extent of motion of'thesame, ofcontrolling and regulating such motion and of furnishing a' continuousand permanent record-of the progress and operation, or motion, ofvehicles so fitted.

"The object of my invention is to provide simple and eflicient'apparatusof this nature which also may advantageously be employed in conjunctionwith devices disclosed in my a plication for Letters Patent Serial No;35,521; q n In the accompanying drawings forming part of thisspecification and in which like characters of reference indicate likeparts in all of theviews, Figure 1 is aside elevation,

' partly section, of my invention. Fig. 2is a top'view of the same, andFig; 3 is an enlarged, vertical view on line A'A ofFig. 1'.

, to a commutator, "as '7'.

Referring now to the drawings,a is a base. or frame which supports,suitably joarnaled,

' spindle b of the centrifugal overnor 0 Whose yoke d is secured to saidspindle while yoke a may slide longitudinally on spindle b, in a,

manner well understoodin the arts .A tubular sleeve 7 is-mounted on therevolving spindle b in such a manner that only longitudinal motion maybe imparted to it by. yoke c, with which it engages loosely, a pin' ffengaging with, and sliding in, a slot on one 'of the standards of frame(1, thus preventing sleeve 7 from turning. A-pin ft on sleeve 7 projectshorizontally to engage with, and impart oscillatory motion to, gearleverg'and switch-lever it, both of which levers are secured to, and,revolubly sup- Ported b a suitably journaled short shaft, as g..witch-lever h is adapted to contact with connecting bars or pieces 6 if.71 secured This commutator j is shown to be made? of tin-insulatingsubstance in the form of a segment provided with a horizontallyprojecting short shaft by means of which, and with the aid of nut 7'',it may be adjustably held in suitable supports or journals as a. Thecenters of the supports for the levers g and h and commutator j arepreferably in the same line.

A graduated scale, as k, is secured to frame a in such a manner thatthepointed end of switohdever it, as well as an index finger secured tocontact piece .2, may

always be in close proximity to said scale, whatever then'v-positlonshould be. The ps riphery ofgearlever 1 has teeth which mesh with theteeth of pinion Zmounted on shaft in, which shaft also carries gear a. Arack 0, slidably niounted in support'c; is adapt ed to receivehorizontal reciprocating mo,- tion from gear a, while a pencilor-stylus72 carried atthe end of said'rack may bear on a suitable sheetor.st1'ip'(n-ot shown) placed on, or around, and lQCLlVlllg uniform mo[tion from drum 3 Drum 9* receives uniform Patented Nov. 23, ENE).

rotary motion aways in the" same direction,

from a spring-actuated motor, as a clock or time-train (not shown), orother suitable motor, a clutch 1" serving to 'discoi'nrect the drum yfrom the motor shaft 5.. An iutermedial-y shaft t which receives rotarymo! tion, in either direction, directly or in directly from one of theaxles or equivalent partof a vehicle, turns gear a which meshesWltll'PlIllOll c on spindle 5,,of thecentrifugal governor c, and therebycauses sleeve f to turn gear-lever gland switch-lever it to ,an

eXtent'varying with the speed of the vehicle,

regardless "of the direction'in which the vehicle is" moving. A spring wserves to connteract the centrifugal force of the governor ballsand toreturn the same to their position of rest, as iswell;understoodfElectrical connection with the, conducting bars or strips, or contactpieces, 22' on comn'iuta tor jis preferablyeffected ili'rOiigIithehollow center of the latter by means of wires or s1m 1lar conductors, asa;

t h The operationof my apparatus is as follows: Assuming the same to beattached to a motor vehlcle or automobile, and shaft 't to rece veIIIOtlOIl from one of the axles of the vehicle, it is obvious that inconsequence of the action of centrifugal force, onthe balls of thegovernor c any increase in the speed of the vehicle willcause gear-leverg and switch-lever 7L to-turn in the direction as indicated by arrows.,7 Contact piece 2' on commutator 7' extends below the latter in theform of an index finger pointing onto graduated-scale k. If commutator jis then turned drawings. Whenever switch-lever it rests on contact piecea vehicle will have reached the predetermine and set limit of speed atthe rate of 30 miles per hour. Should the speed increase beyond the setlimit but a trifle, switclnlever it will continue to turn in thedirection of the ar-' row and thereby break contact with contactstrip'z'in consequence of which the explo sions in the'gas engine cylinder willbecome impossible and the speed be reduced The metallic frame a of theapparatus and switch-lcrer h form part of an electric circuit, orcircuits, comprising a battery or other source of electricity, ignitionapparatus and fuel or actimting-tiuid controlling devices, substantiallyas described in-my ap* plication for Letters Patent Serial No. 375,521,but not shown inthe accompanying electric current is sent through thesame to a device for throttling the fuel or the fluid actuating theengine, and a similar action for a similar purpose occurs whenswitch-lever h rests on contact piece 2"v j By the means beforedescribed the opcrator of a motor-vehicle is enabled to auto-- maticallyprevent his machine from exceeding a pro-determined speed limit, andtovary such limit at will by changing the: po-

sitlon of connuntator, 7', that is, within the capacity or powerof themotor or cngme.

While the operation of the vehicle is thus controlled,.by switch lcverit making and breaking elttctrical circuits for bringing into actionsuitable devices and interrupting the action of others, gear-lever gthrough intermediary members, causes pencil p to record on a sheetcarried by drum 9 by means of a line. the variations in the speed asthey occur in sucha manner that the nearer the line de- "scribed by thepencil is to a line at right turned by clock-work or other motors, ,preh

a v i erably so as to make attained revolution in twelve or twenty-fourhours, such motion, of course, being uniform as well as entirelyindependent ofthe necessarily irregular motion of spindletb ofcentrifugal governor, 0. I As commutator j and smtch-lever k may also beutilized for switching into or outof action other circuits than the onesnamed 7 either in place of, or inf'addition to, the same, I do not wishto confine myself to the arrangement of circuits herein described,

nor to the precise details of construction relating to my indicating,controlling and recording devices.

lV hat I claim as new and desire to secure by Letters Patent is:

1. In combination with a speed recorder a switch comprising a pivotallymounted switch lever actuated by said recorder mechanism, an adjustablecommutator insulated from said switch lever, a contact strip on saidcommutator contacting with said switch.

a switch-lever attached thereto, a stylus,
